My thoughts are closer to Lofton here.  They totally nail how dysfunctional (mainly because of mental illness) this family is.  And they do it in a believable way too.  There's a lot of distance and emptiness and lying going on this house.  Also the house was a character to me.

Agree on Colette nailing the role.  I love how you can kind of slowly see her falling apart.  It culminates with that dinner scene where she totally loses it and rips into the Peter.  At that point, I basically stopped treating her (and Peter) as an objective narrator.  I thought most of the scenes she was basically hallucinating stuff.  That's what I thought the Heridtary part referred to.  That mental illness just ran through that side of the family.  It's probably why the Dad is the only one who is normal here. 

The ending is weird to me.  Because if they wanted to they really, really should have introduced that "aspect" earlier.  I would have found the last five mins more convincing.  As it is, I was like WTF happened here?  It's too bad because the psychological drama aspects of this are great.

On Obsession, I've seen it two or three times and it bores the shit out of me, aside from the ending at the airport. I don't know if it's the subpar acting or a bad script.  I just get nothing from it and don't get why some people think it's one of DePalma's best.  I'd rather watch Femme Fatale or Passion over obsession.

Yeah, I left out the food scenes they are great.  That one scene in the restaurant where he (Scorcese) tracks the characters as they go through there is used all the time now and is very famous.

I love Stone's prime from like 1991-1995.  She took chances after she hit it big with Basic Instinct.

I'm going to watch Hereditary.  You guys are making it way too interesting.  Plus I like Toni Collette anyway.

Triangle: slasher/time travel film.I found it pretty fun just to watch how the main character was going to get out of the loop.  I'm not sure about the ending since there are a lot of meanings/interpretations of it.  Retroactive a 1997 is sort of similar to this.  But Triangle takes place on a boat which makes it interesting.

Network--the last time I saw this was in the early 2000s.  And it's more relevant NOW than it was back then.  Basically, online/the internet could be substituted for Television.  I had no idea how funny this film is, especially Faye Dunaway's Diane character.  Oh, it basically predicted/forecasted the mergers and the harmful intersection of business/big money and the news, which is still felt to this day.  And the rise of live shot/homemade footage would become popular.  As well as glamourizing crimminals/questionable people and making celebs out of them.  Oh one of the best parts (and best acted) of the film is near the end where Max (William Holden) just tells Diane how hollow, shallow and a sad person that she is.  I totally glossed over this the last time I saw this. Faye Dunaway had a great prime from like late 60s-late 70s.  Apparently, the wreck that was Mommie Dearest torpedoed her career along with the fact that she was extremely difficult to deal with.

Trapped--kidnapping film with Kevin Bacon and Charlize Theron, Stuart Townsend, and Courtney Love.  It's pretty good.  Not great or a classic.  Just watchable especially if you turn your brain off.  It was going well 2/3 of the way, then the last 30 mins went off the rails plot wise.  Shoot outs and ridiculous over the top stuff.  There's one key plot that is revealed that gets totally lost and thrown away in favor of the car crashes and etc.  I turned off my brain at that point and just enjoyed the stupidity. 

V  for Vendetta-I saw this in the theater  in 2006 or 2007.  I think it holds up pretty well.  I found the middle slightly long.  They could have probably edited out.  Also I'm not sure whether or not the point where they stage Evie's abduction and captivity is neccesary.  This is basically a modern version of 1984.  There are some nice touches like the jukebox, film posters, watching old fims, in the place where V lives.  And really at this point, I'm not sure it's that far fetched that a nation would kill it's own citizens on purpose to gain power.  Still I really enjoyed the beginning and end of this film.

Funny you should mention the cheese/over the top factor of Scarface. I remember the scenes where they are in the club and that annoying cheesy 80's anthem Push it to the Limit starts playing.

I think some of the really early 80s films (maybe 80 and 81) avoid this cheesiness and still retain part of the grit/realism of the 70s.  Blow Out from DePalma was released in 1981 and still has that ambivalent shades of gray/ feel.  Ditto Thief from Mann in 1981.

Scarface (1983).  There was nothing wrong with this movie but I came away kind of with an eh? reaction.  It's well acted and there are some great set pieces.  So why does this not move me or engage me like Carlito's Way (another Pacino/DePalma collaboration and gangster film) or the Godfather (another 3hr epic from Pacino)?  Pacino is great and gives it his all into the character.  I just don't know why I didn't connect with this on an emotional level.  Oh the fixation that Tony had on his sister Gina was disgusting bordering on incestous.  This is one of those films that's well made but I have no desire to watch for another few years.

Hell up in Harlem--fun blaxplotation film from 1973.  It's obvious this was made with a lesser budget but it didn't bother me.  I had fun seeing the different shot/angles that came from some of the scenes from this film.  It's over the top but that's the fun of watching some of these films.  Pretty good soundtrack too from Edwin Starr.
